The crushing jaws. Blake Crushers are operated by toggles and controlled by a pitman. These are commonly used as primary crushers in the mineral industry. The size of the feed opening is referred to as the gape. The opening at the discharge end of the jaws is referred to as the set. The Blake crushers are single or double toggle drives.Traditional and the new FEA failure models with stiffeners, shows that some 10-25 savings in plate weight may be possible.

Jaw Crushers are used to reduce the size of many different types of materials in many applications. The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers.In this paper, studies into the causes of fatigue cracks of a jaw crusher supporting structure are presented. The problems appeared after short time of operation at a new crushing facility. A large number of fatigue cracks with a high growth rate and bolt failures were observed in the crusher supporting structure. Considering the high dynamic forces that occur during the operation of such.
Keywords- Jaw Crusher, Computer Aided Design (CAD), Point-Load Deformations and Failure (PDF), Finite Element Analysis, Solid Modeling, Corrugated Jaw plate, Stiffened-Jaw Plate. I. INTRODUCTION Jaw crusher is a machine designed to reduce large solid particles of raw material into smaller particles.A crusher jaw that had failed while in service was studied through metallographic techniques to determine the cause of the failure. Our investigation revealed that the reason for the fracture was the presence of large carbides at the grain boundaries and in the grain matrix.
Toggle jaw crushers are constructed for heavy duty fabricated plates with reinforcing ribs throughout. Fixed and movable jaw faces are made up of manganese steel. The working principle of jaw crusher shown below in Figure 1 and the single and double toggle jaw crusher mechanism is.This article analyzes the failure modes associated with the issues of easy-wearing and short service-life of hammer head on hammer crusher under load condition. The key factor of wearing is identified. In applying the invention principle in TRIZ theory while considering the actual working conditions, technological solutions of modular hammer head and rotary hammer head are proposed.
Apr 24, 2018 The construction and working of the crusher in brief The main components of the crusher are Frame, jaw plate, Eccentric shaft, toggle-toggle plate, Fly-wheel, Pulley, Belts, tension spring and motor as shown in figure 1.
